The chaps i order fit great. i did have to trim them, but i expected that. I wore them the first day, took my harley for ride, they felt great in the seated postion and my legs stayed warm in 40 degree weather. A very good investment. Thanks

BEST ANSWER:My husband has a 38" waist. He said he wears these XL chaps on the 3rd hole on the belt, 3rd from the end. A 40" waist might use the 2nd or even the 1st hole. I'm not sure of that will work for you. He likes the chaps, though.
